Comenzando a probar y familiarizarme. Por ahora me parece sencilla y muy intuitiva.
If we could add the contacts directly form google intead of creating list it would be easier for me, apart from that all fantastic.
Nice and easy to set up. Contacts could be organised in a more easy friendly way and also it would nice to be able view mail by name ' A-Z ' or date added ..
Excelente
misleading. claims to have no limits but that is only on paid plans. has limit of100 mails per day like its competitors.
En el momento lo estoy probando y me ha ido de maravilla. Seguimos experimentando sus funciones.
Easy to use
It will take some time to fully learn the entire functionality of the tool, but I completed a simple campaign in under 30 minutes with the assistance of the online videos.
I tried the free version and it has some issue like the email was sent in different language and have difficulty of sending the emails sometimes the email was not sending . I hope you fix It . Because I am planning to try the paid version if this will be fix.
Complessa la creazione delle liste. Non le carica nemmeno salvate in .csv e nemmeno attraverso i fogli google...mistero!
